Coevolution on tunable fitness landscapes
نویسنده
چکیده
I examine the statistical properties of a NKC model of biological evolution in which species interact and compete to maximize their individual fitness. Species are modeled as adaptive walkers moving on deformable fitness landscapes. The nature of these landscapes is controlled by a small set of free parameters; by tuning them, I investigate the different phases of the model and search in particular for a critical phase. The model is also extended to include restricted connectivity between species and also fitness fluctuations dependent on an effective temperature.

Red Queen Coevolution on Fitness Landscapes
Species do not merely evolve, they also coevolve with other organisms. Coevolution is a major force driving interacting species to continuously evolve exploring their fitness landscapes. Coevolution involves the coupling of species fitness landscapes, linking species genetic changes with their inter-specific ecological interactions. Here we first introduce the Red Queen hypothesis of evolution ...
متن کاملCorrelation analysis of coupled fitness landscapes
The correlation structure of fitness landscapes is a much used measure to characterize and classify various types of landscapes. However, analyzing the correlation structure of fitness landscapes has so far been restricted to static landscapes only. Here, we investigate the correlation structure of coupled, or dynamic, fitness landscapes. Using the NKC model of coevolution, we apply a correlati...
متن کاملCoevolution to the edge of chaos: coupled fitness landscapes, poised states, and coevolutionary avalanches.
We introduce a broadened framework to study aspects of coevolution based on the NK class of statistical models of rugged fitness landscapes. In these models the fitness contribution of each of N genes in a genotype depends epistatically on K other genes. Increasing epistatic interactions increases the rugged multipeaked character of the fitness landscape. Coevolution is thought of, at the lowes...
متن کاملB2.7.2 NK Fitness Landscapes
NK fitness landscapes are stochastically generated fitness functions on bit strings, parameterized (with genes and interactions between genes) so as to make them tunably ‘rugged’. Under the ‘natural’ genetic operators of bit-flipping mutation or recombination, NK landscapes produce multiple domains of attraction for the evolutionary dynamics. NK landscapes have been used in models of epistatic ...
متن کاملFrom Royal Road to Epistatic Road for Variable Length Evolution Algorithm
Although there are some real world applications where the use of variable length representation (VLR) in Evolutionary Algorithm is natural and suitable, an academic framework is lacking for such representations. In this work we propose a family of tunable fitness landscapes based on VLR of genotypes. The fitness landscapes we propose possess a tunable degree of both neutrality and epistasis; th...
